Pointing a health bar to client camera

I’m new to networking.
I have a 3D player prefab with a child camera, and a healthbar canvas above the player’s head.

I want all the individual healthbars to point towards the client camera, so they always appear flat to every player, regardless of the location/rotation of the player with the healthbar.

I know this means the pointing of the healthbar has to be client-based, but I’m not sure how to set it up other than that.

Any advice or tutorials welcome, thanks!
